IVIOLDERS FLASK.

SPECIFICATION forming part of Letters Patent No. 451,576, dated May 5, 1891.

Application i'lled July 14, 1890.

To @ZZ whom it may concern,.-

Be it known that I, WILLIAM G. RICHARDS,

a citizen of the United- States, residing at Boston, in the county of Suffolk and State of Massachusetts, have invented certain new and useful Improvements in Molders Flasks, of which the following is a specification.

This invention relates to flasks for casting car-wheels and like articles by the method of filling the mold from the under side thereof, the object being to furnish a flask for such purposes having means for holding in place the cores, and in which the several parts may be readily assembled and taken apart.

In the drawings accompanying and forming a part of this specification, Figure l is a front elevation of a flask embodying my present improvements. Fig. 2 is a central vertical section of the same. Fig. 3 is a plan view of that portion of the nowel-frame or drag on which the pouring-head is set. Fig. 4 is a View of the part. shown in Fig. 3 with the pouring-head in place thereon, the upper end of said pouring-head being broken away.'

Fig. 5is a sectional view of one of the anchorrod holders, drawn on an enlarged scale, and showing the method of adjustably securing therein the anchor rods or wires for holding down the arch-core in a wheel-mold.

Similar characters designate like parts in all the figures.

My improved flask when constructed for car-wheels consists of the nowel 8, provided with the usual lugs 60 for receiving the dowelpins, the chill resting on said nowely and having the usual dowel-pins 85 for engaging said lugs 60 to retain the said parts in place relative to each other, the cope 9 resting on the said chill and being removably secured thereto by the bolts 36, which pass through lugs 62 and 64, formed on the said chill and cope, respectively, and are furnished with the keys or wedges 37. The nowel part 8 of the iiask is set on the usual bottom board 52, the flask being properly located thereon by thedowel-pins 53, which are fixed in the ears 75, that are formed on J[he nowel 8 of the flask. In practice the bottom board 52, and also the partition-walls 46, may be perforated with 5o numerous small holes in a well-known man- Serial No. 358,654. (No modeh) ner to increase their hold upon the material of the mold.

The pouring-head C is shown formed in two parts 66 and 68, which may be held together in any well-known manner-as, for 5 5 instance, by the bolts 3S, that pass through the lugs G5 and 67, formed on said parts 66 and 68. Said head C has the base-ange 39 formed thereon, and which rests on the side Walls and 72 of the projecting part 40 of the nowel-frame S. Oppositely-disposed projections or ears 4l are formed on the flange 39,similar ears 42 being formed on said Walls 7 O and 72, respectively. The pouring-head is held in place by stout wedges or clamps 43, which are driven onto the said ears, thereby7 securely clamping the head C onto the nowel S. The projecting part 40 of the nowel has formed thereon the lugs 44, which serve as stops and engage the projecting ends 45, 7o forming the middle part of the flange 39 for locating the head C properly on the nowel and locking together the two parts thereof.

As shown in Fig. 2, the cope part of the flask is provided with a number of radial partitions 46 and with the central ring 47 for supporting the sand of the cope. A number of anchor-holders 48 (of which four are shown in the drawings) are screwed into the partitions or ribs 4t', and are bored to receive the Wires or anchor-rods 49, by which the archcore 50 is held down during the filling of the mold, said wires being secured by set-screws 5l in the said holders. In practice, after making the mold in substantially the usual manner, the core 50 being set in place and the mold closed, the rods 49 are put in and firmly pushed down through the holders 4S and the perforations in the ribs 4G against said core, when the set-screws 5l are firmly tightened. The mold being filled, the metal of the Wheel W firmly in closes said rods, which may afterward be cut off, leaving the ends thereof remaining in the casting.

' In making the mold the nowel and the cope are handled and made up in the usual way and assembled with the chill in place between them, the core being properly set, as above mentioned, and the nowel having the passageway 7G for inflowing metal and leading from roo preceding description without further explanation.

Having thus described my invention, I

1. In a molders tlask,the combination, with" the nowel-frame having the bottom plate and side walls thereof extended and terminating in an inclined plane,otI the pouring-head correspondinglyconstructed at its base to set on said inclined extension of the frame, and means, substantially as described, for elamping said head in place by engaging the inclined base thereof.

2. In a1nolde1"silask,the combination, with the lower part or frame for the nowel, having' at one side thereof an open extension provided with laterally-prejecting Hanges and with stops, of the pouring-head having corresponding flanges and constructed to set 011 said open extension in engagement with said stops, and means for clamping said head to said extension by said flanges.

3. In a molders ask, the combination, with the nowel-trame having an extension, substantially as described, opening outward and provided with stops for the pouring-head and with projecting flanges on the side walls of said extension, of the pouring-head set on said extension in engagement with said stops and having laterally-projecting flanges corresponding with the Hanges lof the extensionwalls, and clamps engaging said flanges to hold the pouring-head in place.

et. In a molders fiask, the combination, with the nowel-i'ramcand with an extension thereof consist-ing of the lower plate and the side walls provided with anges 42 and with stops 44, of the pouring-head fitting on said walls and engaging between said stops and having fianges 4l corresponding to said fianges 42, and clamping devices engaging said iianges to hold said head in place, the line between said extension and pouring-head being inclined, whereby the vertical ruimer in the pou ri n g-head and the horizon tal runner in the nowel meet at said line.

5. In a molder`s flask, the combination, with the nowel-frame extension having the side walls provided with stops 44, of the pouringhead formed in two parts connected together and fitting on said walls and having the projecting ends 45 engaging between said stops, whereby the head is located on said extension and the two parts of said head are locked together.
